The pitch-black dragon scales slowly dispersed, and the once imposing Dorothy returned to her human form.

The Fairy King, satisfied, muttered something like "I really nailed it this time" and left, leaving the homebody witch with a huge mess to clean up.

"Damn, wasn't it said that the peak was supposed to be unbreakable? How did it shatter so easily?"

Dorothy looked at Duel Mountain Number 8, which had been split in half, feeling completely numb.

She began to wonder if the money she recently earned from customizing spells would be enough to cover the damages.

Yeah, it should be enough.

After all, it's only Arena Number 8 that's destroyed, not the entire Dragon Roar.

She thought about it, then shakily pulled out her spellbook, pondering whether to inform Inanna and ask Miss Tyranny to estimate the cost.

However, she hadn't even composed her message when a message from the other side arrived first.

[Combat Fun: Hey, Dorothy, how's it going over there? Are you alright? I saw a massive black crescent moon fly out!]

[Combat Fun: Damn, how did the arena break? Those array masters must not have maintained the formation properly, letting something like this happen. Damn it, I just sensed the power of the crescent Sword Qi and it wasn't even beyond the standard.]

[Combat Fun: Anyway, I'm really sorry. It's our arena's formation that's not sturdy enough, affecting your duel. Wait a moment while I go deal with those big-mouthed crows, and then we'll talk in detail. I'll make sure to compensate you properly.]

...

Dorothy: "....."

Looking at Miss Tyranny's message, the homebody witch fell into an uneasy silence.

Oh, this honest child, she actually thinks it's her arena's fault and is even prepared to compensate me.

Dorothy couldn't help but place a hand on her chest, trying to soothe her faintly aching conscience.

But hilariously, the front armor was too thick, and she couldn't feel her heartbeat at all. 𝕗𝐫𝚎𝗲𝘄𝐞𝕓𝐧𝕠𝘃𝕖𝐥.𝐜𝚘𝚖

Perhaps only she herself knew that her earlier attack might have indeed exceeded the peak's range.

Destruction Armor, no wonder this technique was once considered Yemengade Shipyard's secret technique, it seems to have touched the edge of Authority.

That was a power only a Sage could master, an ultimate force surpassing forbidden curses.

Even though Dorothy hadn't mastered the true power of this Authority, she had only borrowed a tiny bit of its effect, but the power...

Well, the ruins before her spoke volumes.

"Authority of [Unchangeable], huh? This is quite unexpected, considering Yemengade was best known for Transmigration, yet the Authority it mastered is the complete opposite of the ever-changing Transmigration, [Unchangeable]."

The homebody witch mused to herself, this was the result of her research into that piece of Yemengade's inverse scales.

Yeah, the name [Unchangeable] was something she came up with on the fly; she didn't know the real name of her ancestral elder's authority, so she just called it that. After all, the effect she understood was unchangeable.

What the complete effect of [Unchangeable] Authority was, Dorothy didn't know, but after that battle, she understood the effect of the new generation Destruction Armor she developed.

Effect One: Destruction Armor can mitigate changes brought by external forces.

How much it can mitigate and its limit isn't quite clear yet, but just now, when Dorothy transformed and her entire body was covered with Destruction Dragon Scale Armor, Sitle's Golden Country domain's oppression was almost entirely canceled out.

The domain, carrying the power of the world, tried to weigh her down, to weaken her, but as long as she wore the armor, she remained [Unchangeable], rendering the oppression ineffective.

This is terrifying. To put it simply, all attacks that hit you actually aim to force you to change. If you can remain perpetually [Unchangeable], then there's only one word for it.

Invincible!

Of course, this weakened version of the Destruction Armor's [Unchangeable] Authority couldn't achieve true invincibility, but Dorothy tried to sense the strength of her Dragon Scale Armor just now and concluded that its durability had become infinite.

In other words, unless an attack exceeds the defensive power of the Dragon Scale Armor all at once, any damage it can block can almost be entirely negated. Neither magical nor physical penetration would work.

Attacking the same spot dozens or hundreds of times to gradually accumulate enough damage to break through would no longer work on Dorothy.

Of course, for Dorothy's own Juvenile Dragon scales, the defensive power is actually quite weak, since her true magic power is only 290,000 Mana, just a newbie. She only seemed formidable because, in the Yellow-Cloaked King mode, she had infinite magic power, throwing things with brute force.

But if it's the dragon scales of her ancestral elder Yemengade...

Well, that's truly invincible.

She wouldn't need any other means, all she had to do was wrap her enormous dragon body, large enough to circle the world, around something, and a world would be gone.

Of course, it's basically impossible for the recreated Destruction Armor to reach her ancestral elder's level, but even reaching a thousandth or a ten-thousandth of that strength would be terrifying.

Especially since this armor can negate the world's oppression during conquest wars. The most feared aspect is the world's oppression against invaders—the freshly landed troops in another world could have their strength reduced to a fraction under its pressure. The beginning of a war is quite challenging.
